Student If you cross a red four o'clock flower to a white four o'clock flower, you get a pink flower.
Flower color in four o'clock flowers shows incomplete dominance. If you cross two pink
four o'clocks, what will be the phenotypic ratio?

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
